Here there.
I own a jdm vh41de and I am just interested in swapping to a vh45 crankshaft for a longer stroke and displacement. Looking for good NA power atm.

.Do I need to swap rods and pistons over as well?
. As the vh41 has higher compression, Will the vh45 crank lower my compression down to vh45 specs? If so what are my options for increasing it without blowing a heap of money on custom pistons? Shave head or block?

as I live in australia, where could I find a vh45de crankshaft?

Sorry for noob questions...
thanks! Jacob
